I assume they are two separate patents by two separate companies, but once those are both on the same can opener, there will be no reason to buy any other manual can opener. So when is the first one expiring?

Cans have been around for quite some time, with it, can openers. Given the proliferation of both, I suspect it’s waiting for someone to invent it.
